39.87 is what percent of 2600 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 2600 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 2600, so we can write it down as 100%=2600.
4. We know, that x% equals 39.87 of the output value, so we can write it down as x%=39.87.
5. Now we have two simple equations:
1) 100%=2600
2) x%=39.87
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=2600/39.87
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 39.87 is what percent of 2600

100%/x%=2600/39.87
(100/x)*x=(2600/39.87)*x       - we multiply both sides of the equation by x
100=65.211938801104*x       - we divide both sides of the equation by (65.211938801104) to get x
100/65.211938801104=x
1.5334615384615=x
x=1.5334615384615

now we have:
39.87 is 1.5334615384615% of 2600
